FASTENER FOR DOORS Filed Dec. 22, 1925 2' Sheets-Sheet 2 Patented Aug. 3, 1926.

UNITED STATES CLEMENT V. HILL, OF TRENTON, NEW JERSEY.

FASTENER FOB. DOORS.

Application filed December I My present invention is an improvement in the construction of fasteners for doors shown in my Patent No. 1,123,741 dated January 5, 1915.

p F or the purpose of illustrating my inventi'on I have shown it mounted on a refrigerator deer.

' The object of my invention is to provide a fastening mechanism which will hold the door tightly on lts amb with an air tight joint, said mechanism being so constructed that it may be as readily operated from the inside of the door as of, the latch boltbeing of a type thatwill automatically engage its keeper as soon as the door is closed, there being tension means to hold the bolt firmly in its locked position, but the mechanism for operating the bolt is such that thetension of the said means to overcome, with a minimum pull in the act of opening the door; and with these and other objects in view my invention consists of the parts and combination of parts, as will be more fully hereinafter set forth.

in the drawings:

Figure 1 is a front elevation of a portion of a door and its jamb with my improved fastener applied thereto.

Figure 2 is a vertical. section on the line 2-2, Figure 1. I

Figure 3 is a large detail end view of a door with my invention applied, some of the parts being shown in section. V V Figure 4-. is an enlarged detail rear elevation of the front plate.

Figure 5 is an enlarged perspective detail view sealing plate and operating rod, parts being broken away.

The reference numeral 1 designates a jamb, and 2 a door of suitable construction.

The keeper 3 is secured to the jamb by means of the screws or bolts 4:, and is providedwith a nose 5 having a cam face 6 and a cam face 7, the latter cam face, when the keeper is assembled one. door jamb, being spaced from the jamlo to form a recess '8 for the reception and retention'of the latching bolt. p

A plate face 10 is secured to the door by an suitable means, such'as screws, and'is substantially of-L, shape to provide ja'base upon which the working parts of; the latch may be mounted: thereby eliminating the liability ofthe parts being-lost in transit and reduein'g to a minimum the numberof from the outside therewhen the 22, 1925. Serial No. 77,037;

screws or bolts necessary to secure the parts to a door.

Arms 11 and 12 are formed integral with the base plate 10 and project forwardly therefrom when the plate is secured to a door. A revoluble shaft 13 is journaled in said arms 11 and 12 and is provided with a crank arm 14: on the end of which is mounts ed an antifriction roller 15 which is adapted to enter the recess 8 in the keeper and thereby securely latch the door 'in'its closed position, as shown in the drawing.

An arm .16 is keyed to the'shaft 13 by means of which the shaft is revolved and the. latch bolt withdrawn from the keeper parts are operated in the act of opening and closing the door. This arm is provided with a yoked end 17 to which is pivotally secured a link 18, the end thereof being adapted to receive the forked end 22.

The door is provided with a transverse opening 19, in which the rod or stem 20 is positioned, the opening being, relatively, of greater diameter than the rod or stem shown, the inner end of the rod or stem being provided with a knob 23. The inner end of the opening is closed by means of a cup plate 24- having an opening through which the rod passes, said plate being packed with a packing 25, preferably felt, which will prevent the ingress and egress of air around through the opening 19, which, in the Case, ofrefrigerators, is very essential.

The forward or outer end of the rod is provided with an integral operating handle 2'6 and with a striking plate or lug 27 which is of such size that it will close and seal the outer end of the opening 19, when the door is closed, thus providing another seal against the ingress or egress of air. secure to the operating rod 20 under the lug 27 a resilient packing 28 which functions to reduce the noise of'impact and also as a sealing element. Intermediate the striking plate 27 and handle 26 the rod 20 is enlarged I as at 29 through'which is'formed a slot'30 in which is pivotal'ly secured the reduced up'ae end 1 i ft11 1ink1 n the r duced iow r nd .82 of the pe ink 3 ,121. upper "e d fi h link '33 fbf fl g f ed 15 pi e to' the lug '31 whichlg face plate 34."

The faceplate 10 is, preferably, provided with a flange 35 whereb'ythe plate when secured to the door spa ed therefr in as will be more clearly seen in Figure 3. Cu the rear face of the plate 10, in proximity to the openings 36, I provide slideway 38 on which is slidably mounted the sealing plate 39 which is provided with an opening through which the operating rod passes. will be noted that the sealing plate is gr ater area than the hole in the face la e, whereby the hole 36 is always covered y said plate 39, 'rrespectiie of any 1110?:- ment of the operating rod.

The operating rod 20 is provided with screw threads on which is mounted a tension nut t0 which abuts the short tube 4-.1 loosely mounted on the rod 20. A coilet spring 42 is secured around the rod 20, on end of which is seated against the sealin, plate 39, while its other end is seated on the short tube e1, whereby the spring not only puts the operating rod under tension but it also firmly holds the sealing plate in the slideway 38 and effectively holds'the plate 39 acrossthe opening 36 of the face plate to prevent air from passing the opening 36.

A sleeve 43 loosely surrounds the spring 1-2, tube 41, tension nut and a portion of the operating rod 20 and its forward end ears against the sealing plate 38 which effectively seals that end of sleeve as best seen in Figure 3. The rear end of the sleeve l3 is provided with a shoulder on its rear end which is adapted to bear on the rear plate the sleeve being reduced in exterior diameter forming a rear *ardly projecting lip 46 which passes through an opening in the rear plate 45.

When the door is closed the parts are in the position shown in Figure 2. Now asv on-4 suming that it is desired to open the door the parts are operated, from the outside, by grasping handle26 and pulling it in the natural direction to swing the door open, when the parts will assume the position shown in Figure 3 and by continued pull the door will swing to full open position. When the handle 30 is pulled outward the outer end portion of the rod 26 is elevated, as shown in dotted lines in Figure 3, by reason of the fact that the upper end of the link 33 is anchored to the base plate 10 and swings in an are from that point, and this upward movement results in pulling the link '18 bodily upward thereby, elevating the inner end of the arm 16 and thus revolving the shaft 13 against the tension of the spring 42, thus swinging the arm 1% and elevating the roller 15 above the nose owhereupon the door is free to be swung open. Notwithstanding this vertical movement of the rod 20, the opening 36 in the front plate is al ways closed against the passage of air by the sliding sealing plate 39.

In closing the door the roller 15 rides up througl the cam face 6 and drops into the recess 8 and by the cooperation of the spring 42 and the cam face 7 the door is pulled against the jainb and forms therewith a tightjoint.

In the use of refrigerators it is customary to close the door tightly so that it is necessary to provide some means for operating the latch from within the refrigerator therefore I extend the rod or stem 20 within the refrigerator and provide it with a lrnob 23 so that the ock may be operated by pushing the rod rutward. I prefer to use a knob on the inner end of the rod as it presents an enlarged surface against which the body may be conveniently pressed, in case the operator requires both hands to carry goods from the refrigerator.

It will be observed that in operating this fastener no unusual or unnatural move- Inents are necessary; the natural movement of the in opening and closingthe door being all that is necessary to operate the fastener.

By reason of the link inoveinent herein described which gives a very powerful leverage, I '2-111 enabled to put the spring 42 under very heavy tension which results in a stronger pull of the latching roller 16 on the Call}. face 7, which in turn results in a tighter joint between the door and jainb.

What I claim is:

1. In a fastener for doors, the coinbination with a latch, and a face plate having an opening therethrough, of adapted to pass through the opening in said plate and of materially less diameter than said opening, a sealing plate loosely mounted on said rod and adapted to close the opening in the face plate around saidrod, a coiled spring around said rod, one end of which is sealed on said sealing plate, and a tension nut on said rod against which the other end of the spring is seated.
